Hi guys, I'm new and this is my first post. I've been encountering some problem with my graphic, per the attached pictures. The ways this happens is that when I turn somewhere else, and turn back to that view, that "space" appear, and after I give it a second to "load", it comes out normal again. My guess for this is because my GPU processing power isn't quite enough for the mods I'm using, or for the game for that matter. But any solution or suggestions to fix this would be very lovely, please help.

My PC specs are:

i7 960 @ 3.20 GHz 3.19 GHz
6.00 GB RAM
NVIDIA GTX 560 Ti 2GB (Main GPU)
NVIDIA GTS 450 (PhysX Card, I've been told that this car is bottlenecking my main GPU, and I have turned this off completely and noticed no difference in performance of the main GPU)

Better City Texture by 0hiena0
Road Texture by (I can't remember who)
ENB Series 0.082 Config By !BFT! Clan GTA IV Division Patch 1.0.7.0
SMAA + effect for GTA IV by Legacyy
Obviously a tons of vehicle mods, no EMP since I can't get it to work . Some sound mods.

This feels to me as if it's because my GPU processing power isn't fast enough to set the scenery up before I turn to view it, that's why it's doing this, SLI might be a solution? Opinions greatly appreciated.

I found something about it. I do use the "Native Ingame Trainer". If I go in and play the game regularly, none of this happens. But if I ever have to use the "Teleport" function of the trainer, where the game to recreate a different scenery in a flash, apparently that put a massive strain on the GPU, causing the processing speed to slow down, thus slowing the visual speed. Or maybe I'm just imagining things, could be just the refresh rate problem...? Anyone else got any ideas?

Or could be you have to load new textures into memory. Even though you have a nice amount of VMEM the game will not preload different textures from different areas.

It's a streaming engine, which means if you teleport to somewhere else (distance is not specified in your posts) then the game will have to take that second you described to load something that isn't a temporary texture. Higher resolution textures mean more size and more Video memory used + more time needed to load the texture.

Though judging from your original post you experience this every time, everywhere when you simply turn the camera. I doubt the game engine would need to unload textures, then again I have no idea how much your straining the engine with the additional graphic mods.

I tend to abuse the teleport function quite often, I'm guessing that might be the problem, and the distance is island to island every time I teleport. That might be my problem then, I tested again and again and seems like the only time this happens is when the game having to reload a whole new area, then it starts to strain the speed of the GPU. If I actually take times and drive to objective, it's actually fine.
